Photoresponsive fiber scaffolds with a core–sheath nanostructure for regulating cell behaviors

Abstract

Herein, we report the fabrication of photoresponsive three-dimensional (3D) fiber scaffolds for the first time, where photoresponsive polymers are localized on their fiber surfaces of nano thickness, using a simple and practical co-axial (core–sheath) electrospinning technique. Cell adhesion to the 3D scaffolds was regulated by photostimulation.
